Good catch. The translation of the option descriptions is done as part of the option parser (libgpg-error/src/argparse.c) and thus we need to have gettext support over there. Also for some other error messages.

Seems to work if NLS support is enabled. Updating in https://github.com/Homebrew/homebrew-core/pull/122706. Once merged, users will need to brew reinstall libgpg-error (Homebrew has decided to avoid forcing updates to all users outside of critical fixes).

Probably due to libgpg-error being built without NLS support on macOS as formula currently doesn't have gettext dependency. On Linux, libintl is provided by glibc so doesn't need any extra dependencies.

This is the formula: https://github.com/Homebrew/homebrew-core/blob/c26f1c8714c231ee6796915f033ba229c89af3d6/Formula/gnupg.rb

I have no idea about Homebrew - can you figure out the maintainer and point him to here?

This is the Homebrew build. Maybe something not included in the recipe?

No idea what happens. I can't replicate that on a Linux box using GNU gettext and neither in Windows using gnupg's own gettext implementation. It seems that strings without any line feed don't get translated.

Thanks. Looks pretty standard. I will have a closer look.

It is unlikely that the tofu stuff will get into widespread use in the 2.2 version - if at all.

That seems to (mostly) work partially fix PowerShell pipeline output at least:

Hello again Werner,

Ok, but the problem is that by default CMD command windows do not use any Unicode set of characters, and their default font is 'Raster characters' and the typical display of characters inside these windows, at least for Italian people because this was the default since MS-DOS age, is to only consider using MS-DOS ASCII codepage 850, not Unicode.
And this is also why before showing the error message I ran the command mode.
Anyway because of the 2 characters getting displayed instead of single expected 'è' (whose character code is 0x82) I can also tell you that by using Charmap.exe again (just in case you may not know it allows display of any Unicode or Raster font characters and their hexadecimal codes) and so switching its default font from System (Unicode) to 8514oem (raster, corresponding to 8514oem.fon) I've been able to determine which should be the 2 wrong displayed characters hexadecimal codes : 'Ã' (0xC3), and '¨' (0xA8) but here obviously both characters cannot be represented correctly because this site is using 'Segoe UI' font, which is Unicode too.
So the only main way to check that I identified the correct characters will be if you (or someone else you know) with another Windows client run Charmap.exe switch font to 8514oem (raster) and check that displayed characters corresponding to 0xC3 and 0xA8 are the same that got displayed in the error message bitmap I provided (a part from probably being able to find where in Italian messages localization rather then in source code those 2 characters have been used incorrectly).
P.S. Because in a past similar bug about Italian localization I saw a comment from you about this kind of option, please just let me know in case you think I might possibly be able to help you to review involved 'GPG' Italian error message(s) for this bug.

That pretty much looks like the other errors you have with Unicode characters - which we can't replicate.

Thank you.

Thank you.
I apply Diff1487 then Diff1488.

update

Thank you. Here are my comments.

Hi, I updated the whole file, PLZ review. https://dev.gnupg.org/D533

Thank you for your suggestion and making a patch.

Sorry, I think, it is more official to update from 把密钥导出到一个公钥服务器上 to 将密钥导出到一个公钥服务器上 in the Chinese doc scenario. 😄😄😄😄

Pushed the change.

Considering the history of the translation, I concluded that it should be:
把密钥导出到一个公钥服务器上
(the typo was G-A where B-A was expected.)

@guzhongren
This is not GitHub, so, if you want, you need to learn how to submit your change in the form of patch, by using git.

Clone and checkout the branch as usual with Git. There is no web editor etc like you might know from github. For your request we need to wait for someone to check your request.

Thank you. Merged and pushed.

Thanks for the feedback. I sadly forgot to include the italian translations of GpgOL in the installer. So they will only be part of the next relase.

Problem solved in Gpg4win 3.1.15 version! I think it can be closed!

Hi,
you can close this tickets, the Italian translation has already been uploaded successfully. Don't import anything to GnuPG. Thanks a lot!

Argh! I had added the translation to GpgOL but forgot to list the file in our installer. So it will only be part of the next version.
